SEIBOLD COMPOSER Analyser can perform continuous analysis of heavy metals in water. The colorimetric analysis - stated by the WHO as reliable and best fitting method for online analysis - is used for reliable and accurate results and low total cost of measurement (TCM). Parameters: Aluminium Al (*) Arsenic As Cadmium Cd Cobalt Co ...

Correct measurement results are a prerequisite for compliance with limit values, which are always specified as total metals. Heavy metals such as copper, nickel, zinc, etc. can be quickly and reliably determined in aqueous samples with the help of the LANGE cuvette tests. Matrix factors (e.g. interference ions, colour, turbidities, etc.) may have a negative impact on themeasurement and cause ...

Reagents and chemistry used with SEIBOLD COMPOSER Analysers are free from toxic compounds. Our "Green Thumb" project started in 2006 and delivered its first products in 2008. In 2011 the complete range of SEIBOLD COMPOSER Analyser for Heavy Metals has been introduced to the market. SEIBOLD's Analyser series COMPOSER is based on spectrophotometric technology. Measured concentration is a function ...

This study aims to investigate the ability of low cost ceramic membrane filtration in removing three common heavy metals namely; Pb2+, Cu2+, and Cd2+ from water media. The work includes manufacturing ceramic membranes with dimensions of 15 by 15 cm and 2 cm thickness. The membranes were made from low cost materials of local clay mixed with different sawdust percentages of ...

The chemical composition of the bottom sediment, and more particularly the heavy metals content, reflects human developments and impacts on the catchment and reservoir's natural environment. The bottom sediments of the reservoir retained by the Irkutsk Dam have been analysed. The reservoir is mainly supplied by water from Lake Baikal. The following amounts of heavy metals have been found in the ...

This study focused on the removal of Pb(II), Cd(II), Cu(II), and Zn(II) using reagent solutions by natural limestone in a batch system. The sorbent, collected from the Late Cretaceous limestone beds, Tunisia, was characterised by X–ray diffraction (XRD), chemical analysis (XRF) and infrared spectroscopy (FTIR). XRF showed that the studied limestone contained high amount of calcium carbonates. XRD ...

Water is fundamental to the survival of living beings. It registers every impact and can function as an indicator of environmental stressors. Our objective in the current study was to assess the sanitary conditions of the waters in the Açude, Maria Lucinda and Santa Rosa streams. This was done by checking pH, running quantitative analyses of heavy metals and testing for total coliforms. The ...

Macroinvertebrate species traits, such as physiological sensitivity, have successfully been introduced in trait‐based bioassessment approaches and are important predictors of species sensitivity in the field. The authors ranked macroinvertebrate species according to their physiological sensitivity to heavy metals using toxicity data from acute laboratory assays. Rankings for each of the heavy ...

Attention to heavy metal contamination associated with highways or motorways has risen in the last decades because of the associated health hazards and risks. The present study analysed the metal content in soil samples of one of the main highways along the western part of the Jordanian border, the North Shuna–Dead Sea–Aqaba Highway. The metals analysed were Pb, Zn, Cd, Co and Ni. In the samples ...

The accumulation of heavy metals in plants is a function of uptake capacity and intracellular binding sites. The concentrations of heavy metals in plants growing in constructed wetlands vary considerably between species and systems but in general, the concentrations are within the range commonly found in natural stands. The highest concentrations are mostly found in roots, followed by rhizomes, ...

Accidental spills and improper disposal of industrial effluent/sludge containing heavy metals onto the open land or into subsurface result in soil and water contamination. Detailed investigations are carried out to identify the source of contamination of heavy metals in an industrial suburb near Bangalore in India. Detailed investigation of ground water and subsurface soil analysis for various ...

Most household in Batina depend on private wells for their fresh water supplies. The quality of such water is not regulated or tested by authorities and, therefore, consumers' health might be at risk if water is contaminated. We assessed the contribution of some heavy metals to water pollution. Water samples from 364 houses were collected and analysed for levels of lead, chromium, nickel and ...

The hot-dip galvanising process produces a large quantity of acidic effluent high in iron, zinc and chloride ions. The current method for disposal of the waste acid is to neutralise the remaining hydrochloric acid (HCl) to precipitate a worthless, environmentally harmful mixture of iron and zinc hydroxides that be disposed of to specialised landfill sites. The recovery of any of these species is ...

Low cost Jordanian natural zeolite (ANZ1 and ANZ2) of type phillipsite-chabazite obtained from Jabal al Ataitahat south Jordan were tested experimentally as adsorbent material for the removal of lead (Pb) and lithium (Li) ions from the effluent industrial wastewater streams. The experimental breakthrough curves were obtained from fixed bed experiments and analysed using the Thomas and Yoon and ...

Within the framework of Integrated Water Resources Management (IWRM) the nutrient and heavy metal levels within the Kharaa river basin were investigated. By the application of the MONERIS model, which quantifies nutrient emissions into river basins, various point and diffuse pathways, as well as nutrient load in rivers, could be analysed. Despite seasonal variations and inputs of point sources ...

The accumulation of six heavy metals in fine-grained sediments from the sediments of the late marshes and swamps of southern Iraq is evaluated. The dynamic features of Euphrates and Tigris rivers influence the distribution of the metals in the study area. In the analysed sediments Co, Zn, Cr and Cu concentrations approach the average concentration in the Earth's crust and uncontaminated ...

Landfill leachate samples were collected anaerobically at six locations at the El-Akader landfill site in North Jordan. The collected leachate samples were separated into size fractions with special attention to the distribution of colloids and associated heavy metals. The fraction sizes were 1.2 µm. The maximum concentrations of heavy metals in the analysed leachate samples were Cd 0.6 µg/l, Ni ...

Acinetobacter in surface waters are a major concern because of their rapid development of resistance to a wide range of antimicrobials and their ability to persist in these waters for a very long time. Four surface water isolates of Acinetobacter having both multidrug- and multimetal-resistant ability were isolated and identified through biochemical tests and 16S rDNA ...
